An unexpected change in a student’s behaviour deserves a calm, private conversation.
- Why B fits: Speaking with the student after class provides an opportunity to understand what is happening without embarrassing them publicly.
- Why the others are weaker: Punishment or immediately calling the student lazy assumes a cause before listening. Sending them away may miss a need for support.
- Practical point: Ask open questions, document serious concerns, and follow the school’s safeguarding or referral process where necessary.
